NServiceBus Explanations
2008-03-30 13:36:00 Ayende’s been going over nService Bus, seeing how it’s built, and raising various questions and concerns. I’ll begin by taking them from the outside, in - that is, first API questions, and then internal structure issues. SendLocal First of all, the effect of calling SendLocal on IBus takes all the logical messages passed in (params IMessage[] messages), wraps ... More About: Architecture

I Hate WSDL
2008-03-28 17:44:00 Ted says it really well, and let me add a big +1. Note to those who didn’t attend the session: you didn’t hear me say it, so I’ll repeat it: I hate WSDL almost as much as I hate Las Vegas.

How to create fully encapsulated Domain Models
2008-02-29 15:40:00 Most people getting started with DDD and the Domain Model pattern get stuck on this. For a while I tried answering this on the discussion groups, but here we have a nice example that I can point to next time.

Prevent technology blow-ups from killing your project
2008-02-27 10:08:00 Why should you put a 10 foot pole between yourself and technology? Well, because Microsoft (or insert vendor of your choice here - they’re all equally guilty of this) tend to deprecate (as in kill) the technology they evangelised just last year/month/week. Microsoft Sql Server Notification Services are the latest victim. I hope you don’t have any application code tied to that technology. Not that it’s the only one. Workflow Foundation’s warts have started coming out from behind the shiny veneer. It turns out that the threading model is… problematic and requires all sorts of workarounds. Hope those are stable. It’s not like they could have known that we need a high performance way to run our business logic out of the box. I hope you don’t have to change your application code (sorry, pictures diagrams) when you get blocked threads when trying to cancel irrelevant workflows (customer no longer does business with us - cancel order processing wo...

"High Priced" architects extremely valuable, even when remote
2008-02-25 14:25:00 When I’m working on a thorny architectural problem, I usually give Arnon a ring and after talking things through with him, reach a much better solution than what I previously was convinced of. These calls have been saving my clients months of effort, increasing revenue through shorter time-to-market, and often have lower total cost of ownership by needing fewer boxes and less admins to keep them running. Simply not-needing a BizTalk (roughly $50K for a dual cpu box) and one less Oracle (between $50K to $75K depending on server size) brings you to 6 figures without breaking a sweat. Imagine what you could buy with that. It sucks that not enough people have access to guys like Arnon, but he’s pretty busy with his baby now. Although I’ve been trying to jet to clients providing the same kind of value, I’ve pretty much topped out at 10 of these per year each running about a week on average. Frankly, I don’t think my wife would keep me if I did any more than ... More About: High , Remote , Architects

NServiceBus.com information
2008-02-22 23:44:00 www.NService Bus.com is online. It’s not “done” yet, but I’m pretty sure it’s past time that nServiceBus had its own site separate from this blog. I’m still working out the DNS and other domain forwarding and hosting stuff, but we’re live.

Beware the Data Services Platform (DSP)
2008-02-22 00:03:00 Done it again, the analysts have. Dreamt up a (not) new acronym around SOA, they have. Written up a useless 53 page report on it, they have. The grizzled veterans over at the SOA yahoo group have already weighed in. Back in the beginning of 2006 I called it out as a Common SOA Pitfall. Later on ...
